Queue hanging up, timing and Voice menu not working

HI,

I have 3 problems with the queues. Not sure if they are bugs or I'm doing something wrong:

1. Frequency in caller anouncements: I set it to one minute but it seems to play every 30 seconds

2. Calls are automatically hung up on after a time period of 1:30 to 2:30 mins. I've set the max wait time to 5 mins.

3. The voice menu does not play in the caller anouncements.

I'm new here so any help would be great.

Thanks,

Hayden.
